“While driving at normal street speed collision prevention assist inoperative displayed and car would not accelerate. I was in traffic, but was able to exit and pull over and park, turned car off, & back on. Display reset and car normal. Took to dealership immediately-repair was non connecting pins . Too early to tell if this solves. Upon investigation, this is a common issue with 2014 mb and I want to document this extremely dangerous performance.”

“I have partial video if this incident. Incident occurred at 991 odometer miles. After driving approx. ~300 mostly contiguous, flat, rural highway miles in-between lincoln, ne and st. Louis, mo (heading to atlanta, ga) in approx. 30 weather on dry pavement, the engine stopped producing enough engine power to propel the vehicle at the 70-75 MPH that I was traveling. At approx. 60-65 MPH, I applied additional pressure to the gas pedal which was not effective. …”

“On this day, I was nearly killed in my 2014 mercedes CLA250 4matic that stalled on a highway in new york city. The car has roughly 40,300 miles on the odometer. I was driving on the brooklyn queens expressway at 4:00am. The car's motor stalled and the car came to a stop in the left lane. There were no shoulders. I attempted to get the car restarted but all I got were flashing dashboard lights. I attempted to put up a warning triangle to the rear of the car, but the traffic was moving too quickly for me to safely do that. I sat in my car and buckled my seat belt. …”

“Strong gasoline odor inside the car. Dealer removed the rear seat. Removed left and right fuel tank access covers. Found suction jet pump area wet with gasoline. Found the fuel sending unit left side cracked and leaking. They recommended replacing suction jet pump and auxiliary pump costing $1,571.00. The smell is constant whether moving or not and regardless of location. I cough when driving the car hence I seldom use it. If I can not avoid using the car I open all windows and tell any passenger to avoid smoking to prevent fire. I started to notice this issue mid august 2020.”

NHTSA complaint #11374400, filed 2020-11, 33,500 miles

“Car completely shutoff tonight on the highway and luckily I was able to get pulled over without incident. I had numerous messages on the display, including service required, do not shift gears, visit dealer and esp inoperable, see operator's manual . The car would not do anything once I pulled over, nothing happened when I turned the key, no noises, nothing. Mb roadside assistance came and tried to jump start and disconnect the battery to no avail. So, off on the tow truck it went.”
